A newsletter by Valentina from Optivem on spec-driven development with AI, covering prompt pitfalls, the risk of AI-written tests that merely mirror the code, and the case for executable acceptance-test specs over Markdown specs. It is aimed at software engineers and teams adopting AI coding tools, with code examples and promotion of workshops.
